problems previously in accordance with the model given problem. After given time to solve these, most are not able to solve problems and ask how to solve this problem?. Once
identified, the researchers concluded that students who asked not able to understand the meaning of a given problem and not able menalarkan given problem, and some of them are not
interested to resolve the matter. This indicates that students reasoning in solving trigonometry problems still low and almost every matter of trigonometry is short
Based on the description above, by looking at previous studies as well as studies and facts that occurred in schools, the researchers intend to explore or dig detailed information about
how the student reasoning in problem solving trigonometry in terms of the ability to think logically.
B. Research Questions
Based on the background and identification of problems set forth above, then the question of this study is:
1. How does the student reasoning in problem solving trigonometry in terms of the ability to think logically?
2. How comparison logical reasoning ability of students of high and students are capable of logical being in problem solving trigonometry?
C. Types of Research
This research is a qualitative exploratory study aimed to collect information on students reasoning in problem solving trigonometry based on the ability to think logically. Reasoning
students in problem solving trigonometry can be seen from the behavior of students in solving a mathematical problem-solving task TPMM which reflects the mental activity and through in-
depth interviews.
D. Subject Research
This study will be conducted in high school in Makassar. Measures making other research subjects are:
1. Determine which class research-science class XII students who have studied the matter Trigonometry. XII class chosen with consideration:
a. Students of class XII-Science has followed a series of materials in class X trigonometry previously given teacher at school
b. Character class XII student-IPA relatively well known by teachers and not interfere with the preparation of the UN
c. Activity class XII student-IPA is not too dense, making it easier to conduct interviews
2. Provide initial test in the form of multiple choice questions relating to the logic of what they have learned. The number given problem are 15 questions in the form of multiple
choice. This measure, intended to select students who have the ability to logical high, medium, and low
3. The result of the test is the ability to think logically analyzed to determine the subject to be chosen in the study. Banyanknya research subjects to be selected is 3 1 high logical
abilities, 1 logical abilities are, 1 low logical abilities. 4. Prospective subjects are grouped based on the level of logical thinking ability of
students, which is capable of logical high, medium and low 5. If there is more than one candidate subjects who meet the criteria, then the chosen
subject can: a. express his thoughts. In this case the researchers asked the teacher considerations
for selecting students who are considered quite able to express his thoughts based on observations of the teacher during the learning process going on in class.
b. Subject willingness to participate in the data collection for the study. 6. Candidates selected subject used as subjects in this study.
E. Focus Research
